Daikin DAI-EL® G-912 Fluoroelastomer Terpolymer, 71% Fluorine Content
Categories:	Polymer; Thermoset; Fluoropolymer, TS; Thermoset Fluoroelastomer; Rubber or Thermoset Elastomer (TSE)
Material Notes:	DAI-EL® G-912 is a terpolymer suitable for various peroxide cure systems. DAI-EL® G-912 can be formulated to eliminate the post cure process. DAI-EL® G-912 is suitable for compression molding applications requiring excellent chemical and steam resistance. Used alone or in blends with other DAI-EL® grades it produces finished parts with higher modulus and lower compression set. Typical Applications: O-Rings, gaskets, seals, parts Rheological Properties MDR 2000: Temperature: 177°C Frequency: 100 cpm Strain: 0.5° Test time: 6 min Information provided by Daikin.
